Verify if my answers are correct.
1. The function y=x^3 has undergone the following sets of transformations. If y=x^3 passes through the points (1,1), (3,27) and (4,64), list the coordinates of these transformed points on each new curve.
a) reflected in the yaxis, horizontally stretched by factor of 2, vertically translated 2 units up
Answer:
(1,1)>(2,3)
(3,27)>(6,29
(4,64)>(8,66)
b) Vertically compressed by a factor of 1/2, horizontally stretched by a factor of 4, and vertically translated 6 units down
Answer:
(1,1)>(4,5.5)
(3,27)>(12,7.5)
(4,64)>(16,26)
c)Horizontally streched by a factor of 3, horizontally translated 3 units to the left, and vertically translated 3 units down.
(1,1)>(0,2)
(3,27)>(6,24)
(4,64)>(9,58)
Thanks!
